Abstract

L'invention concerne un tuyau flexible extensible pour transporter un fluide sous pression comprenant : un tube interne (1) constitué d'un matériau polymère élastique conçu pour être étendu le long d'un axe longitudinal à partir d'une condition de repos dans laquelle le tube interne (1) a un diamètre de repos et pour se dilater radialement à partir d'une condition de repos ; une couche textile externe tubulaire (2) ayant un motif étirable, disposée à l'extérieur dudit tube interne (1) de manière lâche par rapport audit tube interne (1) et coaxialement à celui-ci par rapport audit axe longitudinal, ladite couche externe (2) étant conçue pour définir en elle-même une surface externe du tuyau sans d'autres couches ; et des éléments de raccord respectifs pour relier fluidiquement ledit tube à une source d'alimentation dudit fluide et à une buse de distribution de fluide, disposées respectivement au niveau d'une première et d'une seconde extrémité commune dudit tube interne (1) et de ladite couche externe (2) de manière à rendre le tube interne (1) et la couche textile externe (2) solidaires l'un de l'autre en correspondance avec lesdites extrémités, le tuyau étant caractérisé en ce que ladite couche textile externe (2) est obtenue par tressage de fils textiles directement autour dudit tube interne (1) dans une condition étirée longitudinalement par rapport à ladite condition de repos, ladite couche externe tubulaire (2) ayant un diamètre maximal, pouvant être obtenu avec une compression axiale maximale de son motif textile dans la direction dudit axe longitudinal, correspondant audit diamètre de repos dudit tube interne (1) dans ladite condition de repos, ledit matériau textile de ladite couche externe (2) étant un fil non élastique ou un fil ayant une élasticité insignifiante choisie parmi les matériaux suivants ou une combinaison de ceux-ci : polypropylène, polyester, polyamide, polyéthylène, fibres para-aramides.The invention relates to an extendable flexible hose for transporting a pressurized fluid comprising: an inner tube (1) made of an elastic polymeric material designed to be extended along a longitudinal axis from a rest condition in which the inner tube (1) has a diameter at rest and to expand radially from a rest condition; a tubular outer textile layer (2) having a stretch pattern, disposed outside said inner tube (1) loosely relative to said inner tube (1) and coaxially therewith relative to said longitudinal axis, said outer layer (2) being designed to define an outer surface of the pipe by itself without other layers; and respective coupling elements for fluidically connecting said tube to a source of supply of said fluid and to a fluid distribution nozzle, disposed respectively at a first and a second common end of said internal tube (1) and of said outer layer (2) so as to make the inner tube (1) and the outer textile layer (2) integral with each other in correspondence with said ends, the pipe being characterized in that said outer textile layer (2) is obtained by braiding textile yarns directly around said inner tube (1) in a longitudinally stretched condition with respect to said rest condition, said outer tubular layer (2) having a maximum diameter obtainable with axial compression maximum of its textile pattern in the direction of said longitudinal axis, corresponding to said rest diameter of said inner tube (1) in said rest condition, said textile material of said outer layer erne (2) being an inelastic yarn or a yarn having insignificant elasticity chosen from the following materials or a combination thereof: polypropylene, polyester, polyamide, polyethylene, para-aramid fibres.
